. ADVERTISING-01.00:.

To all whom it may concern:

hattan, in the county and State of New York, have invented a new and Im roved Advertising Glock, of which the fo owing is afull, clear, and exact description.

This invention relates to illuminated signs or advertising devices, and has particular reference to means for projecting to any suitable distance and forming in any desired size the simulation of an illuminated clock face.-

Among the obj ects of the invention, therefore, is to provide in a device of this character improved means for projecting time, in the manner just stated, in a satis actory way to different distances and providing also means for displaying upon the clock face a suitable advertisement.

The foregoing and other obj ects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all theviews, and in which- Figure 1 is a diagrammatic perspective view of an apparatus involving the principles of this invention, the main portion of the figure being a representation of a distant clock face; Fig: 2 is a vertical longitudinal'section of t e a paratus; Fig. 3 is a horizontal section; an Figs. 4 and 5 are vertical transverse sections on the. corresponding lines of Fig. 2.

The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

Referring more particularly to the drawings I show at 10 a tubular casing within which are located the principal parts of the apparatus; and at the rear end of the'casing and telescopingtherealong is an auxj iliary' casing 11.

At 12 I show a lamp or source of light, preferably in the nature of a high power electric lamp to which current may be provided by any suitable means. Said lamp is shown as supported upon a bracket 13 adjustably mounted upon a pivot 14:. At 15 I Specification of Letters Patent.

provide a vertically arranged condensing lens preferably of lane-convex construction, the convex sur ace of which is remote from the lamp. This lens is of lar e size and considera le strength and is pre erably supported between the two parts 16 and 17 of a split ring. These two parts are shown-provided with binding screws 18 for securing the lens between them, and the ring 17 is provided preferabl with hubs 17 whereby the rin s and the ens carried thereby are ad'ustab y connected at any desired I mm the lamp along horizontal tubular supports 19 shown as two in number and mounted upon pedestals 20 extending upwardly from the bottom of the eas- .fnother condensinglens shown at 21 is preferably of the same size and general character as the lens 15 and arranged with its convex surface closely adjacent theconvex surface of the first lens. The lens 21 is carried by a supporting ring 22 and secured thereto by binding screws 23 or the like. This ring 22 has hubs 22' through which it is adjustably supported along the tubular members 19. The lens 21 is provided in its center with an axial opening 24 in which is fitted a clock or other time piece 0 of any suitable construction and of comparatively small diameter but of a length sufficient to rovid for the necessary works and to carry in the usual manner the hour and minute hands 25 and 26. The clock characters 27 are arranged preferably upon the convex face of'the condensing lens 21 and hence the hands of the time piece are preferably arranged between the two lenses. It is obvious, however, that the characters and hands may be otherwise related to the lens without affecting the result desired. p

The upper portions of the supporting rings for the condensing lenses are connected to tubular supports 19' whereby the rings are maintained in proper position parallel 'to each other. Adjacent the rear face of ing, the door opening, mally kept closed in end of the casing 11 is lens 30 through which the rays of light are projected by means, above described, within the casing. The lens 30 is carried preferably by a disk or plate 31 from which project rearwardly a plurality of parallel rods 32 arranged coaxially with the tubes 19 and 19' and with which they telescope. These rods 32 cooperate with said tubular supports to provide a stable support for the clock and projecting mechanism within the casing irrespective of all of the adjustments that may be necessary for focusing the apparatus according to different distances;

Having thus described my claim as new and desire ters Patent 1. In a device of the character set forth, the combination of front and rear telescopically arranged casings, the front end of the front casing comprising a disk, an object lens securedto the disk, a plurality of parallel rods extending rearwardly from the disk, a source of light within the rear casing, condensing means including a lens between the source of light and the object lens, said condensing lens having a central hole therein, a time piece fitted in said hole, tubular memhowever, being norpractice. The front fitted with an object invention, I to secure by Letbers supported from the bottom of the casing members, and means securing the condensing lens andtime piece upon said tubular members, with said tubular members during all adjustments of the casing members with respect to each other,

2. In apparatus of the class set forth, the combination of a source of light, a pair of condensing lenses of plano-convex form arranged in alinement with each other and With their convexities adjacent each other in front of the source of light, oneof said lenses having an axial opening, a time piece fitted in said opening, supporting members arranged parallel to the axis of the lenses, means adjustably connecting the lenses to the supporting means maintaining them in proper parallel relation to each other, and a slide support adjustably connected to said supporting means adjacent the time piece, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
